Magnetno vodenje tokamak plazme: uvod
 
V tem predavanju bodo predstavljeni problemi vodenja pozicije, toka in oblike preseka plazme v toroidnih tokamak reaktorjih. Okvirno bo podan pristop modeliranja. Nato bo opisan problem vodenja, začenši z regulacijo toka in pozicije plazme do bolj zahtevne regulacije oblike preseka plazme. Predlagane rešitve segajo od preprostih PID regulatorjev do bolj zapletenih multivariabilnih regulatorjev. Predstavljen bo regulator, ki je izveden v največjem delujočem tokamaku JET (Joint European Torus, Culham, VB), imenovan "eXtreme Shape Controller", z dodatnim sistemom "Current Limit Avoidance", ki je bil izveden za reševanje problema zasičenja tokov v magnetnih navitjih.

Predavanje bo v angleščini.

Lepo vabljeni!

Magnetic control of a tokamak plasma: An introduction
 
 
In this lecture, the problems of position, current, and shape control of plasma in tokamak-type (toroidal) devices will be introduced. Modelling issues will be briefly discussed, and then the control problem will be described, beginning with the control of current and position and progressing to the more challenging shape control. The solutions proposed vary from simple PIDs to more sophisticated MIMO controllers. Eventually, the controller implemented at JET, the eXtreme Shape Controller, will be presented, along with a system, called Current Limit Avoidance, which has been implemented to address the problem of current saturations.
 
Cordially invited!
